Manchester City failed to score a win in English football's Premier League for only the second time in 13 matches this season after drawing 1-all at Liverpool and finishing with 10 men.
Vincent Kompany put City ahead with a 31st minute header but Liverpool were level two minutes later when Joleon Lescott deflected a Charlie Adam shot into his own net.
Substitute Mario Balotelli came on for the Sky Blues after 65 minutes but was sent off 18 minutes later and England keeper Joe Hart produced some fine late saves to preserve City's unbeaten record.
City, on 35 points, stayed five clear at the top from Manchester United with Tottenham Hotspur third on 28 points.
Liverpool moved up to sixth with 23 points.
Earlier, Swansea drew nil-all with Aston Villa in a subdued match at the Liberty Stadium which was overshadowed by news of the death of Wales national team manager Gary Speed earlier today.
